Flavius Valerius Constantinus, Constantine the Great, was the son of Helena and the First Tetrarchic ruler Constantius I. Constantine is most famous for his conversion to Christianity after the battle of the Milvian Bridge where he defeated emperor Maxentius. Before the battle he saw the words "In Hoc Signo Victor Eris" (By this sign you shall conquer) emblazoned on the sun around the Chi Rho, the symbol of Christianity. After placing this Christogram on the shields of his army, he defeated his opponent and thus ruled the empire through divine providence. He also shifted the capital of the empire to Constantinople, establishing the foundation for an Empire that would last another 1000 years. He died in 337 and his sons divided the Roman territories.

This variety appears to be much rarer than RIC VIII's R2 rating indicates. RIC references LRBC and an example from the Chorleywood Hoard found in Hertfordshire, England in 1977. We found only one other example online - in the Forum Members' Gallery.

Hannibalianus, the nephew of Constantine I, was named rex regum et Ponticarum gentium (King of the Pontic Land and Peoples) in early 337. He was to take the place the pro-Roman King Tigranes of Armenia, who had recently been ousted by the Persian King Shapur II. Constantine, however, died on 22 May, before retaking Armenia. Later in 337, Hannibalianus, Dalmatius and many other male relatives, were murdered at the behest of one or all of Constantine's sons (though they denied it). Hannibalianus was the Roman king who never actually ruled any territory.

A very rare commemorative issue struck at Lyon for Constantine after his death. Constantine is most famous for leading the Empire to Christianity. Before the Battle of the Milvian Bridge, he saw "In Hoc Signo Victor Eris" (By this sign you shall conquer) on the sun around Chi Rho. With the symbol of Christ on his army's shields he was victorious.

In February 313, Constantine met with Licinius in Milan, where they developed the Edict of Milan. The edict stated that Christians should be allowed to follow the faith without oppression. This removed penalties for professing Christianity, under which many had been martyred previously, and returned confiscated Church property. The edict protected from religious persecution not only Christians but all religions, allowing anyone to worship whichever deity they chose. A similar edict had been issued in 311 by Galerius, then senior emperor of the Tetrarchy; Galerius' edict granted Christians the right to practice their religion but did not restore any property to them. The Edict of Milan included several clauses which stated that all confiscated churches would be returned as well as other provisions for previously persecuted Christians.

Heraclea, the Greek city of Perinthos, later known as Heraclea Thracica to distinguish it from Heraclea Pontica, is now Marmara Ereglisi in the European part of Turkey. The Roman mint was established by Diocletian shortly before his reform and was in use until the times of Theodosius II. Dates of operation: 291 - 450 A.D. Mint marks: H, HERAC, HERACL, HT, MHT, SMH, SMHT.
